China’s Switch to LNG From Coal Will Cut Global Pollution

To many people, natural gas seems to be more of the same, a continuation of the old fossil fuel path that has driven industrialization, air pollution and global warming.

“> […]  China is currently producing twice the greenhouse gases of the United States. And its emissions are growing rapidly. Its emissions surpassed those of the U.S. in 2006, reached double the U.S. in 2014, and are expected to rise by seven per cent per year for the foreseeable future. China obtains 70 per cent of its electricity from burning coal, by far the worst polluter. China has plans for doubling its use of coal in the next 10 to 15 years. Meanwhile, the emissions from the U.S. have stabilized, partly from a slowing economy, but the biggest effect came from a switch from coal to natural gas. If you replace an old coal power plant with a modern natural gas one, you can cut carbon dioxide emissions by a factor of three.

Natural gas doesn’t cut emissions to zero; it is still a fossil fuel. But it obtains much of its energy from hydrogen, an atom that out numbers the carbon atoms in methane (the key component of natural gas) by 4:1. Natural gas can be burned with much higher efficiency than coal, by use of a combined cycle turbine that harnesses both gas and steam power generation.

China wants to move away from coal, to natural gas, nuclear, and solar. Their chief concern is not global warming, but the horrific air pollution that is killing an estimated 4,000 people per day in China, 1.6 million per year. […]”<
